From Denis Watkins, St Just in Roseland, Cornwall, UK
Beth Morrell makes the excellent point that the modern world is grossly mismatched to the one in which we evolved. The restraints of our evolution on our thinking are there to be seen in our actions. We continue to wreck the planet, render its air toxic, pollute rivers, destroy wildlife and slaughter our own kind. Questions on, for example, the structure of space-time may be beyond us. Another order of intelligence, with means and methods unimaginable to us, may be needed (Letters, 15 February).
